[Dovecot] lib90_cmusieve_plugin.so: undefined symbol: message_decoder_init

[Thomas Harold]

After upgrading our CentOS 5 box to the latest revisions last week 
(including Dovecot 1.1), we're seeing the following error message in the 
log files.  Sieve was working fine with Dovecot 1.0.

I have yet to turn up anything via Google for this particular error. 
SELinux is not logging any error messages at the moment, so I'm pretty 
sure that we've properly allowed all the SELinux permissions.
